making jackets

[AndyHass]

The only 10mm jackets I can find are too short for what I'm thinking of doing.  What is / how difficult is the process for making one's own jackets from tubing?  What is a source for jacket tubing?

Thanks....

You can get a Jacket Reducing die (JRD) set to reduce jackets made for .44 or 45 caliber pistol bullets for your 10mm.
To make jackets from copper tube for your 10mm you would use 1/2" tubing, and after making the 50 caliber jacket, reduce it to work in your 10mm core seating bullet die. Type 'L' or 'M' is most often used for jackets. Your local hardware store can order it for you. It comes in 10' lengths and as prices are coming down now it's much more  economical than it was 3 months ago. You will need a way to cut it to consistant lengths, and you'll have to have a Tube Jacket making kit ( very pricey) as well as the JRD ( only about $50 from C/H).  Tube jackets have thick walls normally suitable for only rifle bullets or pistol bullets where you need a lot of strength. It is my opinion that a person only make tube jackets if there were no other way to get them. There are plenty of 44 or 45 cal pistol jackets around that will be a lot less work to use.

Andy you can make a jacket from just about any copper or brass tubing or cartridge brass, hobby tubing.
I use type M to L copper pipe or K. Also copper flashing scrap or sheets.
Or you can get jackets from C&H like Talon mentioned or from Corbin.

Thank you for the information.  I guess what I am trying to conceptualize is how you cup a tube open on both ends into a jacket sealed at the bottom (can you tell I'm new to this process?).  Although I see some of the rifle bullets pictured above have an opening at the base of the boattail and are not fully cupped so apparently it can be done that way too without sealing one end?

On the top row of the picture third from the left is a finished jacket.
The base is closed to a point where you cant see light looking through the base.
Here is an illustration what you need for dies for tubing.
You can also get dies for using strip copper or copper sheets.

Very helpful!  Thank you.  Man this looks like an expensive process judging from the dies I have priced...

LeadPot, what do you use to cut your tubing? I am making 35 caliber tubing jackets but am looking for a faster and more accurate way to cut up the tubing.

Thanks,
Dan

I use a miter box with a 100 tooth carbide blade.
Just fasten a board on the back stop and cut through it that will hold the jacket for a clean cut.
I clamp a stop to the back stop so all are uniform in length.

i use a barker horizontal mill and a costell jewlers saw like corbin sells.
to cut the tubing.

9mm cases can be used for 40cal and 10mm jackets.
